WIRE-CUTTINGRDE VICE Specification of Letters Patent.

Patented May 26, 1908.

To all whom it may concern:

Be it known that I, CHARLEs BURDIoK, acitizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Wire Cutting Devices, of which the following is a specification.

This invention relates to wire cutting devices and consists of certain improvements in the construction thereof as w1ll hereinafter be fully described and pointed out in the claims.

The invention is illustrated in the accompanying drawing as follows:

Figure 1 is a plan view. Fig. 2 an elevation of the same. Fig. 3 is a section on the line 3-3 in Fig. 2.

The invention is shown asapplied to the shanks of tinners shears.

11 marks the blades of the shears which are ivoted on the pin 2, and 33 the shanks of tl ie shears. A gear segment 4 is arranged on the end one of the shanks and a gear segment 5 is pivoted on the other shank. Gear segments 4 and 5 are in mesh. The gear 5 may be operated by a lever 7. 1

It will readily be seen as the gear segment 5 is operated it acts upon gear segment 4 to give relative movement to the shanks 3 so that the shears may be operated with any desired leverage. This part of the construction is not novel.

Arranged in each shank equally distant from the pivot of the shanks are circular openings 8. These are ordinarily formed by simply drilling through the two they are assembled. Dies 9 are inserted in these 0 enings. These dies are provided with a p urality of cutting o enings 10 of different sizes, the openings 0 the same size in the two dies being in register with the shanks in one osition so that a wire 11 may be passed t irough them and out off by the relative movement of the shanks. The dies are held in place by the set screws 12. By making both dies round and supplying each shank with such a die a lurality of openings may be readily supplied and different sizes of wire may be advantageously out without adjustment of the dies.

What I claim as new is:

The combination of the shanks 3, pivotally secured together and having the circular openings 8 concentrically arranged with relation to the pivots of the shanks; and the dies 9 seated therein, having corresponding cutting holes of difierent sizes correspondingly arranged in said dies.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
